A Novel Continuous Method to Trace the Key Eigenvalue Jacobian of Matrix in Power System Voltage Stability
A continuous method to trace the key eigenvalue of Jaeobian matrix is presented. Firstly, a index is found based on the the first and second sensitivity of eigenvalue real-part to bifurcation-parameter. Then, a few eigenvalues are chosen as candidates by the application of the index. At last the continuous method is used to trace the key eigenvalue until the Hopf bifurcation is appear.
